Adaptive Capacity Indicators for HUC-8 Watersheds in US FWS Region 3

This file contains five metrics that were selected to collectively represent the adaptive capacity of each of the 360 HUC-8 watersheds in US Fish and Wildlife Service Region 3 (Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin). The metrics were: percent cultivated, density of dams, projected increase in developed land cover, landscape diversity and local connectedness. Percent cultivated land cover was obtained from the National Agricultural Statistics Services 2018 Cultivated layer and was calculated by dividing the number of cultivated grid cells by the total number of grid cells in each watershed. Density of dams was calculated as the number of dams per area of the watershed using the 2018 National Inventory of Dams from The Army Corps of Engineers. Projected increase in develop land cover was estimated using projections of future land cover developed using the USGS’s FORE-SCE model for the conterminous United States by taking the total number of grid cells classified as developed land cover and dividing by the total number of grid cells in each watershed and then calculated the difference between the future (midcentury) and baseline periods. Landscape diversity and local connectedness were both created by The Nature Conservancy’s Resilient Lands Mapping Project and were calculated as the average score among all the grid cells within each HUC for each metric. All of these metrics were min-max normalized and combined to create the adaptive capacity component of the climate change vulnerability index for Region 3 of the US Fish and Wildlife Service.
